FOXBOROUGH – The spy games are on, and Bill Belichick isn’t worried at all.

Outside of Tom Brady and Bill Belichick and his staff of coaches, there may be no one person with a more intimate knowledge of how the New England Patriots’ offense operates than Deion Branch, who spent seven years in the system before signing with the Indianapolis Colts earlier this week.

But Belichick isn’t worried about what trade secrets Branch may share with the Colts this week. In fact, he says putting stock in such things is “way overrated.”

“A lot of times the information in those situations is sometimes misinformation,” Belichick said. “Sometimes things change from when the person was … I’m not saying in any particular circumstance, just in general. Players come in from another team tells you this is what they do, this is their call, this is this, this is that, and then it turns out that isn’t what it really is.

“We have enough trouble doing all the things that we do, and getting it right, and getting it ready and doing it well, and I’m sure they have the same thing. With the amount of volume you have in your different systems and the amount of volume you face on the other side of the ball. To be able to mentally know everything that you’re doing but also figure out everything that they’re doing – it’s pretty overrated.”
